America was bombed 1,000 times during World War II

Among the lesser known weapons used in World War II were airborne bombs, that drifted across the ocean like flying jellyfish. They were known as fugo, or fire balloons, and they were the only successful attack on the mainland United States.

Drifting across the skies above the Pacific Ocean, during 1944 and 1945, were nearly ten thousand bombs. Although Japan couldn't match the size and population of a larger country, there were ways to turn the sheer size of the United States against it. The established air currents helped, but even with the wind cooperating, it takes navigation to fly to Japan. The continental United States is a bigger target that can be reached with less technology.
